Question

Write an equation of a line with an undefined slope and passing through the point (-2,4).

Hint: To answer this question, consider the type of line that has an undefined slope. Then write an equation of that line using the values in the ordered pair.

Answer 1

Here the hint is quite handy.

An undefined slope means the slope would be something like 1/0 because you cannot divide by zero. This means an undefined slope (or an infinitely large slope) is the slope of a vertical line. The X- value will never change.

SO based on this info, what would it be?

Answer 2

Here, it might be a bit confusing.

Basically undefined slope means a vertical line (i.e. x = 1 or x = -7). Since it goes through (-2,4) and the X - VALUE DOES NOT change, what would it be?

Answer 3

-2?
